Looking for a good job Scheduler / Batch Processer

I am looking for a Unix software package to help us schedule jobs to run automatically in a timely efficient manner. Desired features: * Useable from a variety of IS applications sitting on top of Unix: Red Brick Data Warehousing Oracle Universe future?? * Ability to submit and manage regular periodic jobs; e.g.: monthly, quarterly, 3rd Thursday of the month, etc.. * Allow multiple queues, perhaps different queues owned by different users or groups. * Allow single-threading (e.g., job A needs to finish before Jobs B & C are allowed to begin). * Respect Unix- or application-level permissions & security. Do not allow users to submit jobs they would not otherwise be allowed to run. * Good operator interface: monitor performance turn scheduler & queues on or off historical data and statistics * End-user interface: submit jobs cancel jobs reschedule jobs show job status * Are there other significant features you like or wish you had that I have missed? I welcome all advice, product recommendations, or warnings. Thanks in advance, Charles Stevenson cdstevensn@aol.com or stevenc@hlthsrc.com Charles D. Stevenson 22501 SE 243rd Pl.
